adding food to the library database, NOT working for me

First of all I think this is a very good app for android, most complete I've seen so far, but I have a problem when adding food manualy to the database. I cannot add the value of, for instance, protiën wit a , or a . dor example protiën 28,3 or 28.3 it says there is no value... I can only add normal number like 28 or 4. Is this a known problem? I have a Samsung Galaxy S2

I think it just wants whole numbers, so I would round up or down. Most food labels, at least in the US, use whole numbers.

Ok thx. On the website I can add it so will look for a solution.
